A display server extension point specifies a mapping entry between a display server name against the display server implementing class name. Note that all display server implementations must subclass the base display server implementation provided i.e. org.eclipse.birt.chart.device.DisplayAdapter and override methods as needed. A display server provides generic services to a device renderer such as text metric information, device specific image loading and other system information.</p>
<br>
<ul class=ConfigMarkup id=attlistDesc>
<li><b>name</b> - The name of the display server refers to a tag used to locate the display server implementing class. The naming convention uses a prefix of 'ds.'. Examples of display server names are ds.SWT and ds.SWING</li>
<li><b>server</b> - The server attribute corresponds to the fully qualified class name that represents the implementing display server class. An example of the fully qualified display server class name is 'org.eclipse.birt.chart.device.swt.SwtDisplayServer'</li>
</ul>
<br><h6 class=CaptionFigColumn id=header>Examples: </h6><extension
         point="org.eclipse.birt.chart.engine.displayservers">
      <displayserver
            server="org.eclipse.birt.chart.device.swing.SwingDisplayServer"
            name="ds.SWING"/>
      <displayserver

<h6 class=CaptionFigColumn id=header>API Information: </h6>Please refer to the javadocs for the IDisplayServer interface in the <i>org.eclipse.birt.chart.device</i> package.
<p></p>

<h6 class=CaptionFigColumn id=header>Supplied Implementation: </h6>The <i>org.eclipse.birt.chart.device.extension</i> plug-in provides implementations of the DisplayServer extension point.
